uppercase usernames

[Julien Coloos]

Hi,

Is your system RedHat/CentOS/Fedora ?
I think their version (since 2.3.x) have a patch that "normalize" 
(lowercase + strip leading and trailing whitespaces) authentication ids. 
>From what I could see it appears it was added as a configuration option, 
but the code is not complete and so the default value (enabled) applies.
